What it does

Fluxa connects to any Stremio-compatible addon and turns it into a proper Android app: a home feed with genre and category browsing, a calendar of upcoming episodes, a library with continue-watching and resume positions, and two-way watch tracking with Trakt, MyAnimeList, and Simkl. Playback runs through Media3/ExoPlayer and MPV, including direct torrent/magnet support, with no telemetry.

The Android shell handles all platform I/O — HTTP, Room, ExoPlayer, audio, notifications — but the actual decision-making lives in fluxa-core, a headless Rust library that runs the same logic across Android and desktop targets. Rust never touches the network directly; it emits typed effects that the Kotlin layer fulfills.

Features

• Catalogs & discovery — home feed, genre/category grids, search across every installed addon, and a calendar of upcoming episodes for what you're following
• Library — watchlist, continue watching with resume position, and custom collections, with import support for existing lists
• Watch tracking — two-way sync with Trakt, MyAnimeList, and Simkl
• Playback — subtitle and audio track selection, intro/outro/recap skip, and direct torrent/magnet support
• Profiles — multiple local profiles on one install, each with its own library, addons, and sync accounts
• Addons — install and manage Stremio-compatible addons directly from the app
• TV-ready — a dedicated Android TV / Google TV interface, not a stretched phone layout
• Auto-update — checks for and installs new versions in-app

Variant	Package	Target
mobile	com.fluxa.app.mobile	Phone & tablet
tv	com.fluxa.app.tv	Android TV / Google TV

Each variant ships per-ABI APKs — pick the one matching your device, or let the in-app updater do it for you:

ABI	Devices
arm64-v8a	Most phones/tablets/TVs from the last ~6 years
armeabi-v7a	Older 32-bit ARM devices
x86	Intel-based Android (emulators, some set-top boxes)

Building from source

git clone https://github.com/FluxaMedia/fluxa.git
cd fluxa
./gradlew :app:assembleMobileDebug
# or for TV
./gradlew :app:assembleTvDebug

Prerequisites

• JDK 17+
• Rust stable with the Android NDK targets (aarch64-linux-android, armv7-linux-androideabi, i686-linux-android)
• Android NDK (version pinned in app/build.gradle.kts)
• fluxa-core checked out as a sibling directory (../fluxa-core) — it also provides fluxa-streaming-engine (../fluxa-streaming-engine)

The Rust libraries (fluxa_core, fluxa_streaming_engine) are cross-compiled for all Android ABIs automatically as part of the Gradle build; no manual cargo build step is needed.

Architecture

Fluxa is split into two native Rust libraries and an Android Kotlin shell:

┌─────────────────────────────────────────────────────────┐
│                  Android (Kotlin + Compose)              │
│   UI · ViewModel · Repository · OkHttp · Room · Player  │
├───────────────────────────┬─────────────────────────────┤
│      fluxa_core           │    fluxa_streaming_engine    │
│  Headless brain: state,   │  Video proxy, Dolby Vision   │
│  policy, stream planning  │  rewrite, torrent engine     │
└───────────────────────────┴─────────────────────────────┘

Rust never calls the network directly. Instead it emits typed effects that Kotlin executes:

Kotlin  →  dispatch(action)
        ←  { state, effects: [{ id, type, payload }] }
Kotlin  →  executes each effect (OkHttp / Room / audio / ...)
        →  completeEffect({ effectId, result })
        ←  { state, effects: [...] }

This keeps fluxa_core fully portable — the same crate compiles for Android (JNI), desktop (native Rust), and future targets without any platform-specific code inside Rust.

Platform roadmap

Fluxa for Android ships phone, tablet, and Android TV builds today. The UI is being migrated to Compose Multiplatform so iOS can use the same application interface, while tvOS uses the same shared domain logic with native system integration.
